Operation
Defrosting
The frequency of defrost depends on the usage,
(door openings) and ambient (outside)
temperatures. It is time to defrost when the
refrigerator builds up 1/4 inch of ice on each side
of the cold plates.
The best way to defrost the refrigerator is to
remove all the food, and place a towel inside the
fridge, on the bottom of the cabinet(s). Turn the
thermostat to the “O” position.
Never use a knife to scrape ice from the cold
plate. This will rupture the cold plate and let the
refrigerant escape.
Cleaning
The best time to clean the fridge is after a defrost. Wipe the
inside clean using a non abrasive
cleaner(watered down) for the hard to
clean stains. We recommend baking soda
as the first choice for a cleaner.
If you notice your refrigerator running
longer than normal, clean the condenser
(usually required every few years).
Our units are easy to operate. We use one
thermostat, whether you have a single door or two-door
model.
This thermostat is a full range thermostat that will
maintain your unit at the temperature you desire. Turning
the control all the way to the right (clockwise) will give
you the coldest position, and turning to the left will give
you a warmer temperature in the fridge. The control is
also an on/off switch when you turn it to the “O” position
(hard left). A good setting to start with is #2.
